Set Up the Test

CTOD Fracture Toughness Template

The MTS ASTM E1290 CTOD template complies with ASTM E 1290 - 07 for determining the fracture

toughness value of materials.

The CTOD template provides all the components you need to run a test, analyze the test data, and create

reports of the results.

Control modes

The template guides you through the steps of running a test and provides all the software components

you need to run a test in one of two control modes:

• Crack opening displacement (COD)—The test uses a COD gage signal to provide control feedback.

• Displacement—The test uses a displacement transducer signal to provide control feedback.

Features

The main features of the CTOD template are listed below:

• The main template window guides you through setting up all test parameters, performing crack size

checks, precracking the specimen, and running the test.

• As the test runs, you can stop the test to change test parameters.

• Comprehensive runtime views help you monitor test progress.

• Tabular and graphical displays make it easy to review test results.

• Analysis definitions provide all necessary analysis calculations and views to analyze test runs.

• You can modify the analysis method and reapply the calculations to the data.

• Report templates help you generate reports for analysis runs.

Set Up a Test

To create and run a new test:

1. Create a new test from a template.

a) Click File > New > Test from Template.

b) In the Create from Existing Test window, select a test.

c) Click OK.

The new test is automatically created and assigned a default name. You can change the name and
